[GRASS-user] v.delaunay again - HUGE memory use

Back to v.delaunay... I got GRASS built and running on OSX 10.5 64bits. v.delaunay nows continues to run without memory allocation errors. The big question, why the HUGE memory requirements, or is something wrong.

Here's what I got watching it run:

Virtual memory use steadily climbed into the GBs.

Scratch disk usage also went into the GBs, but stayed slightly lower (probably some compression?).

Very little CPU usage, as it was all disk IO.

I gave up at 18GB vmem / 15GB scratch and killed it.

This is with 2.6 million points.

It seems, that v.voronoi and v.delaunay work only with small datasets.
See probably related bug:
